Mining in Minnesota Minnesota DNR

2021-10-29  Minnesota is the largest producer of iron ore and taconite in the United States. Even though nearly all of the high grade natural iron ore in Minnesota has already been mined, advances in technology have found a use for lower grade iron ore, called taconite.

Commercialization of Taconite MNopedia

2021-10-19  Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn’t until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...

Taconite Minnesota DNR

2021-10-28  Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.
